To all whom; it may concern.-

Be it known that I, LOUIE T. LA PAUGH, a citizen of the United States,residing at Utica in the county of Oneida and State of New York, haveinvented certain new and useful Improvements in Outlet-Boxes; and I, dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, whiohform a part of this specification.

The invention relates the accomto new and useful boxes for electricconduits, and consists in the provision of a novel manner of fasteningthe cover to the box, involving a savingof labor and material andproviding a secure and inexpensive fastem'ng means, doing away withinwardly or outwardly bent ears which are commonly formed upon junctionboxes and which are In order to make steel drawn boxes with ears bent atright angles to the wall of the box, a very ductile and high grade steelmust and in so doing, the operation of blanking and drawing a boxwithout heating or reheating, hardens the steel to such a de, gree thatit is very difficult to bend the parts of the box at right angles to thesides without breakage, for the reason that theoperation of drawing abox out of one piece of steel will necessarily destroy or weaken thefiber of the metal, thereby weakening the cars at the point of bending,and it is the aim of the to produce a box without any inwardly oroutwardly extending lugs, to obviate these objections.

More specifically, the present invention comprises means for fastening acover to an outlet box comprising posts which have split ends adapted topass throughan aperture in the bottom of thebox and be turned inopposite directions, securely anchoring the posts, While the upper endsof the posts are adapted to pass through apertures in the cover andmeans for holding the cover over the upper ends of said posts.

My invention consists fiirther in various construction which will beherein after fully described and then specifically de finedin theappended claims.

are fastened to the box ing passed through said apertures and said endsbent at right angles to the len th of the posts and clenching the bottom0% and are preferably located adjacent to the opposite side walls of thebox in order not to interfere with the conduits which may. be

passed through the walls of the box.

has lugs D about the edge thereof desi ned to engage over the edges ofthe box to 101d the same against a lateral movement, and said cover isprovided with slots Eadapted to receive said posts, as shown clearly inthe drawings.

In Figs. 1 and 2 of the drawings, I have shown the posts as providedwith apertures N which are adapted to receive the ins which, after thecover has been placed upon the box, are passed throu h said aperturesand form keys to securely ho d the coverin place.

In Figs. 6 and 7 I have of the posts as similarly constructed, each ofthepost, t

erturein the upper end are turned down over th 1e sp ends B same manneras t e lugs at the lower end are shown as rectangulanshaped in crosssection,

by the split ends b'e- D designates the cover of the box which end beingsplit and instead of forming an apthe box I shown the two ends e cover,clenching the upper surface thereof in the I 4 scribed, a sim clenched,thusforming a secure means for holding the cover in place.

From the foregoing it will be noted that by the provision of the meansshown and dele and eflicient locking mechanism is alfor ed for securelyholding a cover to an outlet box by the utilization of keys passingthrough the apertured posts orformagainst the bottom of the box or thecover, in

in the opposite ends of the (posts with the spit ends which are clencherespectively,

I the manner shown and described.

That I claim is 1. An outlet box having slots in the bottom thereof,posts passing through said slots and fastened to the bottom of the box,a-

. cover having slots to receive said posts, and

ends of said posts being apertured, and eys thereof, posts having splitends passing through said a ertures and adapted to old-the 'eo-ver upont e box, as set forth.

3. An outlet box having slots in the bottom assing through said slotsand adapted to be c enched against thebottom of the box, a cover havinslots to 'receivesaid posts, and means for i ho ding the posts in saidslots of the cover, as

set forth. 7

4. An outlet box having slots in the bottom thereof, posts having splitends passing through said slots and clenched against the bottom of thebox, a cover, slots therein adapted to receive said posts, and lockingpins passing through apertures in said posts and earing against theouter face of said cover,

as set forth.

In testimony whereof I hereunto aflix my signature 1n the presence oftwo witnesses.
